Fatty liver disease can develop quietly.
In fact, many people with metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as nonalcoholic fatty liver disease (NAFLD), have few or no noticeable symptoms — especially in the early stages.
That’s one reason the condition may be discovered during routine blood tests or imaging performed for another reason.
When symptoms do occur, they can be easy to overlook. Here are seven signs associated with liver problems that may be worth discussing with a healthcare professional.
## 1. Persistent Fatigue
Feeling tired occasionally is normal.
But persistent or unexplained fatigue can occur in people with fatty liver disease.
Fatigue is extremely common and can have many causes, so feeling tired does not mean that you have a liver condition.
If your fatigue lasts for a long time or interferes with everyday activities, consider discussing it with a healthcare professional.
## 2. Discomfort in the Upper Right Abdomen
Your liver is located primarily in the upper-right portion of your abdomen.
Some people with fatty liver disease experience mild pain, pressure, or discomfort in this area.
The sensation may be subtle rather than severe.
Abdominal discomfort can have many causes, however, so medical evaluation may be necessary to determine what’s actually responsible.
## 3. Loss of Appetite
Changes in appetite can occur with many illnesses, including some liver conditions.
If you suddenly have much less interest in food — particularly when accompanied by other unexplained symptoms — it may be worth mentioning to your doctor.
Loss of appetite alone isn’t enough to identify fatty liver disease.
## 4. Itchy Skin
Persistent itching can sometimes occur in people with more advanced liver disease.
However, dry skin, allergies, medications, skin conditions, and many other issues are much more common causes of itching.
Unexplained itching that persists deserves medical attention, particularly if other symptoms are present.
## 5. Swelling in the Abdomen or Legs
Advanced liver disease can interfere with the body’s normal fluid balance.
This may contribute to fluid accumulation in the abdomen, known as ascites, or swelling in the legs.
These aren’t typical early symptoms of simple fatty liver.
They can be signs of more serious liver problems and should be evaluated by a healthcare professional.
## 6. Yellowing of the Skin or Eyes
Yellowing of the skin or whites of the eyes is known as jaundice.
It occurs when a yellow substance called bilirubin accumulates in the body.
Jaundice can have several causes and is not specific to fatty liver disease. However, it can be associated with significant liver or bile-duct problems.
New jaundice should be medically evaluated.
## 7. Dark Urine or Unusually Pale Stool
Changes in urine and stool color can sometimes accompany liver or bile-duct disorders.
Very dark urine or unusually pale stool — particularly when combined with jaundice — should not simply be ignored.
There are other possible explanations, so a healthcare professional can help determine the cause.
# Why Fatty Liver Can Be Difficult to Notice
One of the most important things to understand about fatty liver disease is that you may have it without feeling sick.
MASLD often produces few or no symptoms.
Risk is higher in people with certain metabolic conditions, including obesity, type 2 diabetes, insulin resistance, high triglycerides, high cholesterol, and metabolic syndrome.
However, fatty liver disease can also occur in people who don’t appear overweight.
That’s why symptoms alone aren’t a reliable way to determine whether someone has fatty liver disease.
# How Is Fatty Liver Diagnosed?
You cannot reliably diagnose fatty liver disease simply by looking for symptoms.
Healthcare professionals may consider your medical history and risk factors and use tests such as:
* Blood tests
* Ultrasound or other imaging
* Specialized tests that estimate liver stiffness or scarring
* In selected cases, liver biopsy
The appropriate tests depend on the individual.
# Can Fatty Liver Improve?
The encouraging news is that lifestyle changes can make an important difference for many people with MASLD.
For people who are overweight or have obesity, gradual weight loss may help reduce liver fat and improve liver health.
A balanced diet, regular physical activity, maintaining a healthy weight, and managing conditions such as diabetes, high cholesterol, and high blood pressure can also be important.
There is no single “detox” food or drink that magically cleans fat from the liver.
Long-term lifestyle and medical management matter much more.
# The Bottom Line
Fatty liver disease can be surprisingly quiet.
Fatigue and discomfort in the upper-right abdomen can occur, while symptoms such as jaundice, abdominal or leg swelling, and persistent itching may be associated with more advanced liver disease.
But none of these symptoms can diagnose fatty liver disease on their own.
If you have persistent symptoms or risk factors such as type 2 diabetes, obesity, high cholesterol, or metabolic syndrome, consider discussing your liver health with a qualified healthcare professional.
Early evaluation can help identify liver problems before serious complications develop.
